Description

Show Description

Named for a beast that survived ice ages, the bison is crammed with almost a kilo of heat-trapping down. Designed for Denali, Aconcagua, the Himalaya, or anywhere that mistakes could be really quite dire. Huge V-block side baffles and horizontal baffles across your chest hold the down in place. Double interlocking draft tubes and a filled collar seal in heat and security while frigid winds snuffle around the tent.

  • Shell, collar, and draft tube are GORE™ WINDSTOPPER® fabric, which is light, compressible, and impervious to the elements.
  • Deep hood is well filled, and has a large integral hood ruff to seal your face from the elements.
  • Offset, insulated double draft tubes ensure the down doesn't migrate and create cold spots.
  • #5 YKK locking zipper.
